    • Abstract


      The configuration of valvula cerebelli and torus longitudinalis shows distinct variations at the level where the tractus mesencephalocerebellaris posterior establishes full connection with the granular valvula in the four species ofAmblypharyngodon. The taxonomic value of the configurational variations of mesencephalon of the four species has been discussed.
